One of the greatest things about technology isn’t what it does, but it’s what it can do. This is a shining example of this very concept:
If you have a point-and-click digital camera made by Canon, you may be able to turn on all sorts of features usually reserved for more expensive SLRs. That includes live histograms, depth-of-field calculation, under and overexposure highlighting, and — best of all — shooting your pictures in RAW. The secret is CHDK, an enhanced, free software replacement firmware.
I’m going to have to disagree that the best part of this is being able to shoot in RAW mode. Don’t get me wrong, I love using RAW (or NEF as it’s called on my Nikon) but the best part of this enhancement is that fact that you can do scripting in a BASIC like language in the camera. Wow… This is like getting a computer that has predefined programs on it and then discovering the programming tools for it. With these scripts you can do such amazing things as automatically create a series of photos for HDR stacking that can later be run through software to extend the dynamic range of the images. You can run an interactive interval timer to take X number of photos ever X seconds, minutes, or even hours so you could do a time laps study of ice melting or a building being built. Those are just two examples of what can be done with the powerful feature.
One clever thing is that if you make a mistake and screw something up that chance of you ‘bricking’ your camera is quite low. To remove the firmware enhancement you simply remove the CD card and power up the camera. Bingo, everything is back to normal. I for one will be on the lookout for a camera that this will work on.

I don’t usually toot my own horn but this time I’m going to. I was recently asked if MAKE magazine could use a few of my photos of a Halloween display that I had made a few years ago. I agreed to it of course, I mean who wouldn’t want to see their photos in a national magazine? So I signed some paperwork and waited for the issue to hit the stands. All my waiting paid off when I saw the issue on Saturday and saw my photos printed up in glorious color. My photos of glow sticks, black light, and electric arcs fit right in with the other amazing projects that are being showcased in the Halloween issue. If your looking for a way to add a little something to your garage turned haunted house or even if your just wanting to scare the crap out of a coworkers with some automated nasty in the cube farm this is the magazine to buy!

This is a rather unusual application of magnetic principals. The nail polish is applied in a normal way but before you let it dry you hold the magnet (included with the bottle) over the wet polish and let the magnetic particles that are suspended in the pigment arrange themselves. When the lacquer dries the metallic particles are frozen in place and you get some clever patterns. I’m not a user of nail polish myself but I bet I could think of some science projects that this stuff would be good for.
